For a shot like this, use classic transparent-product lighting rather than front-lighting the bottle directly. The example image is using a dark-line/black-line approach: a bright background shows through the clear bottle, while the bottle edges stay defined by darker lines.

A tabletop light box or light tent is a practical way to do it. Use a white seamless background and large, diffused light sources, then place the main light above and slightly behind the bottle. That back/top lighting helps the gel remain clear while giving the bubbles shadow and definition so the contents are visible.

Key points:

• Light the background and tent, not the front of the bottle.
• Keep the light large and soft for smooth reflections.
• Position the light slightly behind and above the product.
• Adjust bottle-to-light distance to control edge definition and bubble contrast.
• Control exposure carefully so highlights stay clean and don’t blow out all detail.

If you want the opposite look, a white-line technique uses a dark background to create bright edges, but the linked example is closer to dark-line lighting.
